如何选择某一标高上的多义线？
如如Private Sub JoinPoly()Dim SSet As AcadSelectionSet
Dim UseElevation As Double
Dim N As Integer
Dim fType(0 To 1) As Integer
Dim fData(0 To 1) As Variant
Dim det As String
fType(0) = 0: fData(0) = "LightWeightPolyline"
fType(1) = 38
If Not IsNull(ThisDrawing.SelectionSets.Item("JoinPoly")) Then
Set SSet = ThisDrawing.SelectionSets.Item("JoinPoly")
SSet.Delete
End If
Set SSet = ThisDrawing.SelectionSets.Add("JoinPoly")
For N = 0 To 7
SSet.Clear
fData(1) = H(N)
SSet.Select acSelectionSetAll, , , fType, fData
det = axSSet2lspEnts(SSet)
SSet.Clear
'使用SendCommand方法完成连接操作
ThisDrawing.SendCommand "_PEDIT" & vbCr & "M" & vbCr & det & vbCr & vbCr & "J" & vbCr & "0.001" & vbCr & vbCr
Next N
End Sub
我在图纸上画有不同高程上多义线，想选择特定高程上的线图。H(I)为模块级Private double
SSet.Select acSelectionSetAll, , , fType, fData提示出错，不知是什么原因？
请高手指点
fType(1) = 38 的用法是否有错？
